形容词与副词的比较级规则变化和不规则变化 大多数形容词（性质形容词）和副词有比较级和最高级的变化，即原级、比较级和最高级，用来表示事物的等级差别。原级即形容词的原形，比较级和最高级有规则变化和不规则变化两种。 1.规则变化 单音节词和少数双音节词，加词尾-er，-est来构成比较级和最高级。 构成法 原级 比较级 最高级 一般单音节词末尾加-er,-est tall taller tallest 以不发音的e结尾的单音词和少数以- le结尾的双音节词只加-r,-st nice nicer nicest 以一个辅音字母结尾的闭音节单音节词，双写结尾的辅音字母，再加-er,-est big bigger biggest "以辅音字母+y"结尾的双音节词，改y为i，再加-er，-est    busy busier busiest 少数以-er,-ow结尾的双音节词未尾加-er,-est clever/narrow cleverer/ narrower cleverest/ narrowest 其他双音节词和多音节词，在前面加more，most来构成比较级和最高级 important/ easily more important/ more easily most important/ most easily 囧记单词 速记英语单词 单词不用记 2.不规则变化 原级 比较级 最高级 good better best well（健康的） worse worst bad ill（有病的） old older/elder oldest/eldest much/many more most little less least far farther/further farthest/furthest 3. 和more有关的词组 （1） the more…the more… 越……就越……。 （2） more B than A=less A than B    与其说A不如说B。 （3） no more… than… 与……一样……，不比……多。   no less… than… 与……一样……。 （4） more than 不只是，非常。 4．the+形容词/副词比较级+of the two “两个中更……的那一个”  5．最高级后表示比较范围的介词使用。例如:  Han Meimei is the youngest ______ all the students.  A. in    B. than    C. of     D. over  【答案与解析】在最高级后通常会用一个in或of引导的介词短语来表示比较的范围。in表示在一定场所、范围内进行比较,of则表示与同类对象进行比较,故该题选C。 (1) Just now Jim tells me his mother was ill.
